Hoa-.AIR REGISTER.

`The Schedule referred to in these Letters Patent and making of the same.

ing hot-air registers :(such as are used in connectionv with hot-air furnaces for Warnung buildings,) as to make them adj ustableand xed at any point that may be desired. i 1j I have found, by experience, that the ,registers that `are now made are very uncertain, with reference to making themY stay atany desired point. They must, necessarily, n iove easily.` `The register may be closed tight, and a person or persons walking over it will jarit open; or it maybe open, audit will be accidentally closed by thek same causes. They cannot be adjusted so as to allowaslight current ofr hot airto enter the room, and remain so with certainty. I have often noticed that persons, While standing on the registers to warni their feet,`willtonch the star-centre; or the corrugated Wheel atr the-end, and thus unconsciously c lo'se, or vpartially fclose it, when not desired.

My invention makes the adjustment, at any desired l point, au absolute certainty.v

To enable othersskilled in the art to make and use my invention, AI will proceed to describe its construction andioperation.'

I make my registers ,of lthe usual form, of any de- 2 s ireddesign, or'similar to that shown at plate 1 of theaccompanying drawings.`

Underneath this screen, I adix a box, or frame of'v iron, plates 2 and-3.` y

" In the bottom of this are ttedthe valves'or blinds,

plate 5, letter Q, and plate 3, letters Q Q Q.Y

ing-rod S.

`The blindsare then connect-ed together by a slat,

1etterYN, pl'ate 3 and plate 7.

To this slat is again attached a connecting-rod, S,

which again connects with the adjustable lever, plate At the short end of the lever, letter M, the attachi ment is made that Works ythe blinds, by the connect- At the long end of the lever is. attached a brass knob, letter P.

This knob traverses in the arc S T, plate 1, of the screen.' The brass knob isin a recess of the screen, below the surface, and the lever is under., the screen. To open the valves, the knob is pushed to the point S, plate l.' To close the valves, it is pushed toward the point T, plate l. To adjust the valves at any desired point, a turn Aof the knob runs 'the level-P M close up, and secures it to the'under side of the screen.

It will thus be seen that the valves can be easily and quickly adjusted and xed at any desired place, with a certainty of their remaining so.

Plate 11 is simply a cast plate, that is riveted at each end of the box, plate 2, and in which the pivots ofthe valves are itted.

WhatI claim as my inventiona1ul desire to secure by Letters Patent, is

The construction of a register for the'discharge of hot air, in suc-ha way that the valves may be adj usted and xed at any desired point,substantially as described, and for the purposes mentioned.
